Start open OD matrix job

Creates a job to generate an open-ended origin-destination analysis. Unlike Closed OD, callers supply anchor zones and the API returns all counterpart zones observed across the requested flow types (I:I, I:E, E:I, E:E). Set generateTimeSeries to true to produce time-series breakdowns.

Request Body

Analysis parameters.

application/json: object

Name	Type	Input Shape	Values	Description	Value Required
`aggregationUnits`	array<string>	-	hour, dayofweek, daytype, daytypehour	Time-series dimensions to generate when generateTimeSeries is true. Valid values: hour, dayofweek, daytype, daytypehour. An empty array generates all four.	N
`customAggregationValues`	array<object>	aggregationValue: string; hourEnd: integer (int64); hourStart: integer (int64)	-	Custom hourly range buckets appended to the time-series output in addition to any aggregationUnits selections.	N
`dateRanges`	array<DateRangeDto>	dateFrom: string; dateTo: string	-	Date ranges to include in the analysis. Maximum 4 non-overlapping ranges, each up to 365 days. Results are aggregated across all ranges unless isTrendAnalysis is true.	Y
`daysOfWeek`	array<DayOfWeek>	-	1, 2, 3, 4, 5, 6, 7	Days of the week to include (1=Sunday … 7=Saturday). An empty array includes all days.	N
`externalZoneFilterRadius`	integer (int64)	-	-	Radius (km or miles, matching isMetric) used to limit external zones returned. A value of 0 applies no filter.	N
`externalZoneType`	string	-	-	Zone type of the external zones returned for I:E, E:I, and E:E flow types. Required when non-I:I flows are selected. Accepted values (case-insensitive): State, County, City, TAZ, ZIP, CTR, FSA.	N
`generateTimeSeries`	boolean	-	-	When true, a time-series breakdown child analysis is generated for each aggregation unit. Results are retrievable via GET /api/v2/origin-destination/open-matrix/{id}/time-series once the job is complete.	Y
`industries`	array<IndustryGroup>	-	agriculture, mining, utilities, construction, manufacturing, wholesale, retail, transportation_and_warehousing, information_and_cultural, finance_and_insurance, real_estate, science_and_technology, management, administrative_and_support, education, health_care, arts_and_entertainment, accommodation_and_food, public_administration, other_services, unclassified	Named industry IDs from GET /api/v2/filters/industries (e.g. 'manufacturing', 'retail'). Resolved to NAICS codes at query time and combined with any naics values. Leave both industries and naics empty to include all industries.	N
`isMetric`	boolean	-	-	When true, distance values are returned in kilometres; when false, in miles. If omitted, defaults to the isMetric setting on the authenticated user's profile.	N
`isTrendAnalysis`	boolean	-	-	When true, results are returned per date range instead of aggregated across all ranges. Applies to both the primary output and the time-series output.	N
`naics`	array<integer (int64)>	-	-	Explicit raw NAICS integer codes to filter by. Combined with any industries values. Leave both naics and industries empty to include all industries.	N
`percentiles`	array<integer (int64)>	-	-	Percentile values (1–99) to calculate for journey distance, duration, and dwell time. Defaults to [15, 85] when omitted.	N
`timeFrom`	string	-	-	Start of the time-of-day window. Defaults to 00:00:00 when omitted.	N
`timeTo`	string	-	-	End of the time-of-day window. Defaults to 23:59:59.999 when omitted.	N
`tripChainCriteria`	object	maxStopDuration: integer (int64); shortJourneyDistanceThreshold: number (double)	-	Trip-chaining criteria. Omit or send zero values to run without trip chaining.	N
`vehicleClassIds`	array<string>	-	-	Vehicle class filter IDs from GET /api/v2/filters/vehicle-classes. IDs must use the scheme_vehicleClassIndex_categoryIndex format and share one scheme. An empty array includes all vehicle classes.	N
`vehicleClassSchemeId`	integer	-	-	Vehicle classification scheme, from 1 through 5. Defaults to 2 (FHWA/GVWR) when omitted.	N
`vehicleClasses`	array<object>	vehicleType: string; weightClass: string	-	Vehicle class filters. Use an empty array to include all vehicle classes.	N
`vocations`	array<VocationID>	-	1, 2, 3, 4, 5	Vocation IDs from GET /api/v2/filters/vocations. An empty array includes all vocations.	N
`zoneFlowTypes`	array<ZoneFlowType>	-	I:I, I:E, E:I, E:E	Zone flow types to analyse relative to the anchor zone: I:I (Internal-Internal), I:E (Internal-External), E:I (External-Internal), E:E (External-External). Values are case-insensitive. An empty array includes all four flow types.	N
`zoneIds`	array<string>	-	-	Encoded anchor zone IDs. Provide either zoneIds or zones, not both. At least one anchor zone is required.	N
`zones`	array<object>	code: string; iso_3166_2: string; type: string	-	Anchor zone objects for the analysis. Provide either zones or zoneIds, not both. At least one anchor zone is required.	N
